Rotational speed progress bar with background

Who it’s for

Maintenance engineers, machine operators, and plant supervisors ask “can I see rotational speed position within its operating range?” The background variant adds a full-card color signal for wall-mounted displays.

What it does

A device reporting rotationalSpeed = 1200 RPM renders a horizontal bar filled to 24% of the 0–5000 RPM range on a card whose entire background fills with the operating level color: blue for Low (below 500 RPM), green for Normal (500–1500 RPM), orange for Elevated (1500–3000 RPM), and red for High (above 3000 RPM).

• Full-card background color makes rotational speed operating level readable across a room without reading the number
• Horizontal progress bar shows position within the 0–5000 RPM operating range
• Shows one asset’s data per widget; add multiple widgets to monitor different motors or drives side by side

How to set up

Data keys

Key	Role	Type	Description
rotationalSpeed	Bar value	Timeseries	Rotational speed in RPM; change the key name to match your device’s telemetry key

The widget ships with a simulated function datasource key labeled Rotational speed, so it draws random values until you point the datasource at a device and rename the key.

To point it at your own device: open the dashboard in edit mode, open the widget’s Datasources, pick the entity or entity alias, and replace the function key with the key your device reports.

Value ranges

Range (RPM)	Level	Color
0–500	Low	Blue
500–1500	Normal	Green
1500–3000	Elevated	Orange
3000+	High	Red

How to customize

• To change the operating thresholds — open the widget settings and adjust the band boundaries to match your machine’s rated speed range.
• To change the background colors — edit the background color for each operating band in the widget settings.
• To change the bar range — adjust the minimum and maximum values in the widget settings to match your machine’s full-scale speed range.

Tips

• On a control room wall display, the colored background announces motor status from across the room while the bar shows the exact fill level.
• Use this card when the dashboard is viewed from a distance, such as a mounted monitor in a motor control center.
• Use consistent operating colors across all rotational speed widgets.
